Portable acoustic holography systems for therapeutic ultrasound sources and associated devices and methods

摘要

The present technology relates generally to portable acoustic holography systems for therapeutic ultrasound sources, and associated devices and methods. In some embodiments, a method of characterizing an ultrasound source by acoustic holography includes the use of a transducer geometry characteristic, a transducer operation characteristic, and a holography system measurement characteristic. A control computer can be instructed to determine holography measurement parameters. Based on the holography measurement parameters, the method can include scanning a target surface to obtain a hologram. Waveform measurements at a plurality of points on the target surface can be captured. Finally, the method can include processing the measurements to reconstruct at least one characteristic of the ultrasound source.

1. A method of characterizing an ultrasound source using acoustic holography, the method comprising:
obtaining a transducer geometry characteristic, a transducer operation characteristic, and a holography system measurement characteristic, wherein obtaining the transducer geometry characteristic comprises obtaining at least one of an aperture size, planar or curvature characteristic, orientation, or shape of a radiating transducer; instructing a control computer to determine holography measurement parameters; based on the holography measurement parameters, scanning a target surface to capture waveform measurements at a plurality of points on the target surface; using the waveform measurements to define a measured hologram at the target surface; and processing the measured hologram to reconstruct at least one characteristic of the ultrasound source.
